Saliva Management

What can be done for Mike's dry mouth? - Dry Mouth Scenario

After complaining about his dry mouth at his next chemotherapy treatment session, Mike was referred to a Speech Pathologist by the clinical nurse specialist who oversees his treatment. After talking to Mike and investigating all possibilities, the speech pathologist concluded that Mike's dry mouth is most likely a secondary symptom from his chemotherapy. Therefore, as chemotherapy cannot be stopped, it will be important for Mike to treat the symptoms of dry mouth to relieve the discomfort he is experiencing. There are several behavioural treatments that Mike can begin:

Sip water frequently throughout the day, and in particular, keep a drink on his bedside table to sip throughout the night.
Use specially designed products which help to lubricate the mouth, such as Biotene mouth spray during the day and Biotene moisturising gel at night (the effects of the gel are longer lasting so more suited to night-time use).
Sleep on his side to reduce mouth breathing.
Use a humidifier during the night, as the water droplets in the air ensure constant lubrication of the mouth and throat when breathed in.
Chew sugar free gum. Not only does the chewing stimulate the flow of saliva, but by being sugar free it doesn't add to the difficulties Mike may experience with dental hygiene as a result of the dry mouth.
Include plenty of sauces or gravies with meals as this lubricates the food to ensure comfort while eating.

There were also some substances that Mike should attempt to avoid, as they have drying effects on the mouth. In particular for Mike the alcohol, smoking and coffee were a problem. Mike did not realise that these contributed to the discomfort he was experiencing and so vowed to stop the smoking and alcohol, and drink tea instead, cutting down to three cups a day. Though tea contains caffeine and also has a drying effect on the mouth, Mike and his speech pathologist both agreed that he should not have to sacrifice everything he enjoys in life.

It was also recommended to Mike that he make regular appointments with his dentist whilst undergoing his chemotherapy. A lack of saliva can result in impaired oral hygiene, causing dental caries and lesions in the mouth, and the dentist would have the expert knowledge to advise on appropriate care for Mike's mouth, and provide treatment if required.
